[0022] Please see Figure 1-8 This utility model embodiment provides a lamp body connection structure compatible with multi-process lampshades, including: The lamp body 1 has an upper frame 11 on its edge, and the inner sidewall of the upper frame 11 has a plurality of buckle parts 2. The lampshade 3 has an edge that extends upward to form a lower frame 31. The outer periphery of the lower frame 31 is provided with a latch 4 that cooperates with a plurality of the latches 2.

[0023] In this application, the fastening part 2 and the locking part 4 cooperate to achieve rapid assembly between the lampshade 3 and the lamp body 1, and the structure between the assembled lamp body 1 and the lampshade 3 is firm. In addition, the fastening part 2 in this application can cooperate with both injection-molded lampshade 3 and blow-molded lampshade 3. Therefore, when producing lampshade 3, lampshade 3 produced by injection molding and blow molding processes can also be adapted to the fastening part 2, without the need for additional mold development, thereby reducing mold development costs and lowering overall production costs.

[0024] In this embodiment, several latching parts 2 are evenly distributed in the circumferential direction of the upper frame 11, so that when the latching parts 2 and the latching parts 4 are engaged, the lamp body 1 can be subjected to force evenly.

[0025] In a further embodiment, such as Figure 2 As shown, the buckle part 2 includes a buckle plate 21 perpendicular to the upper frame 11 and a plurality of ribs 22 connecting the buckle plate 21 to the upper frame 11; the plurality of ribs 22 are disposed on the side of the buckle plate 21 away from the lamp body 1.

[0026] In this embodiment, the latching part 2 is assembled from a latching plate 21 and a rib plate 22. The rib plate 22 can increase the strength of the latching plate 21 and improve the overall strength of the latching plate 21. In this embodiment, the rib plate 22, the latching plate 21, and the lamp body 1 are all integrally molded.

[0027] In a further embodiment, such as Figure 2 As shown, the lamp body 1 is provided with a plurality of guide members 5 for guiding the latching part 2 and the latching part 4 to cooperate; the plurality of guide members 5 are disposed on the inner side of the plurality of latching parts 2. In this embodiment, the plurality of guide members 5 are evenly distributed on the lamp body 1.

[0028] In this embodiment, by setting the guide 5, when the lampshade 3 and the lamp body 1 are assembled together, the lower frame 31 can fit with the upper frame 11 along the guide 5, thereby facilitating the assembly of the lampshade 3 and the lamp body 1.

[0029] The guide member 5 in this embodiment has the following specific structure: several guide members 5 include a guide plate 51 fixedly disposed on the lamp body 1, and the guide plate 51 has a guide bevel 52 inclinedly disposed on the side near the buckle part 2.

[0030] In this embodiment, a guide bevel 52 is provided on the guide plate 51, and the guide bevels 52 on several guide plates 51 cooperate to form a frustum-shaped structure. Thus, when assembling the lampshade 3, the lower frame 31 can slide along the guide bevel 52, allowing the lower frame 31 to slide along the frustum-shaped structure composed of several guide bevels 52, thereby enabling the lower frame 31 to more smoothly engage with the upper frame 11, further facilitating the engagement of the snap-fit ​​part 2 and the snap-fit ​​part 4. Furthermore, the guide member 5 in this application also serves as a limiting and fixing element, used to limit and fix the assembled lampshade 3, effectively preventing the lampshade 3 from detaching from the lamp body 1.

[0031] In addition, the guide plate 51 in this application has an L-shaped structure, and two adjacent guide plates 51 are symmetrically arranged on the lamp body 1.

[0032] The guide plate 51 in this application has an L-shaped structure, which not only increases the fixing area between the guide plate 51 and the lamp cover 3, but also improves the strength of the guide plate 51.

[0033] In a further embodiment, such as Figure 2As shown, a guide notch 53 is provided on the guide slope 52. The guide notch 53 divides the guide slope 52 into a first slope 521 closer to the lamp body 1 and a second slope 522 farther from the lamp body 1. When assembling the lampshade 3, the lower frame 31 can be slid along the second slope 522 first, so that the edges of the lower frame 31 are all in contact with the guide notch 53. Then, the lower frame 31 can be pushed along the first slope 521, so that the several latches 4 on the lower frame 31 can simultaneously engage with the latches 2, which is beneficial for the rapid assembly of the lampshade 3 and the lamp body 1.

[0034] In a further embodiment, the outer corners of the guide plate 51 are rounded to prevent scratches.

[0035] In one embodiment, such as Figure 3 , Figure 4 and Figure 5 As shown, the bayonet portion 4 is a bayonet groove 41 that passes through the lower frame 31.

[0036] In this embodiment, the bayonet groove 41 is disposed through the lower frame 31. This type of bayonet groove 41 is usually disposed on the injection molded lampshade 3.

[0037] In a further embodiment, such as Figure 6 As shown, an annular recess 32 is provided around the lower frame 31; When the buckle part 2 is engaged in the slot 41, the upper frame 11 cooperates with the annular recess 32, and the outer side wall of the upper frame 11 smoothly cooperates with the outer side wall of the lower frame 31.

[0038] In this application, by reserving an annular recess 32 at the edge of the lower frame 31, a smooth surface can be formed on the outer edges of the lower frame 31 and the upper frame 11 when the upper frame 11 and the lower frame 31 are fitted together, making the lamp body 1 and the lampshade 3 more aesthetically pleasing when combined.

[0039] In another embodiment, such as Figure 7 and Figure 8 As shown, the lower frame 31 includes a first connecting edge 23, a second connecting edge 24, and a third connecting edge 25 connected in sequence; The first connecting edge 23 is connected to the edge of the lower frame 31, and the first connecting edge 23 is arranged in the radial direction inward of the lampshade 3; The second connecting edge 24 is arranged along the axial direction of the lampshade 3; The third connecting edge 25 is arranged in the outward radial direction of the lampshade 3; The first connecting edge 23, the second connecting edge 24 and the third connecting edge 25 cooperate to form the bayonet part 4.

[0040] The lampshade 3, formed by blow molding, is a closed or semi-closed hollow shell with a relatively thin wall. The bottom of the lampshade 3 typically has a large opening for installation, and the edges may be designed with simple rolled edges or grooves for fixation. In this embodiment, a first connecting edge 23, a second connecting edge 24, and a third connecting edge 25 are provided on the blow-molded lampshade 3. These three connecting edges cooperate to form a snap-fit ​​portion 4, which can engage with the snap-fit ​​portion 2. Therefore, the snap-fit ​​portion 2 structure in this application can also be adapted to the blow-molded lampshade 3.

[0041] In addition, the bayonet portion 4 formed by the cooperation of the first connecting edge 23, the second connecting edge 24 and the third connecting edge 25 forms an annular groove on the lamp cover 3, so that the lamp cover 3 can cooperate with the lamp body 1 at any angle.

[0042] In a further embodiment, such as Figure 8 As shown, the distance between the third connecting edge 25 and the first connecting edge 24 is H1; The distance between the side of the buckle plate 21 closest to the lamp body 1 and the end of the upper frame 11 is H2; H2 is greater than or equal to H1.

[0043] In this embodiment, H2 is set to be greater than or equal to H1, so that when the buckle part 2 and the latch part 4 are engaged, the buckle plate 21 can be engaged between the first connecting edge 23 and the third connecting edge 25, so that the buckle part 2 can be more compatible with the latch part 4.

[0044] In this application, a latching part 2 is provided on the inner side of the upper frame 11 of the lamp body 1, and a corresponding latching part 4 is provided on the outer side of the lower frame 31 of the lamp cover 3. During assembly, a firm mechanical connection is formed by the direct snapping of the two.

[0045] Inside the latching part 2 of the lamp body 1, there are evenly distributed guides 5. Their guide bevels 52 together form a frustum-shaped guide surface. During assembly, the lower frame 31 of the lamp cover 3 first slides in along this bevel and is automatically guided and corrected to a position aligned with the upper frame 11, so that the latching part 4 can accurately and easily align and fasten with the latching part 2.

[0046] By designing two compatible snap-fit ​​structures 4, compatibility with lampshades 3 produced by different processes is achieved. For injection-molded lampshades 3: the snap-fit ​​4 is a snap-fit ​​groove 41 that penetrates the lower frame 31, and the snap-fit ​​plate 21 is directly snapped into the snap-fit ​​groove 41. For blow-molded lampshades 3: the first connecting edge 23, the second connecting edge 24, and the third connecting edge 25 formed by bending the edge of the lampshade 3 constitute a non-penetrating hook-shaped structure as the snap-fit ​​4, and the snap-fit ​​plate 21 can be firmly snapped into it.

[0047] In another embodiment, this utility model provides a ceiling light, including the above-described lamp body connection structure compatible with multi-process lampshades.

[0048] Compared with the prior art, this application has the following advantages: (1) High compatibility and cost reduction: The same lamp body 1 connection structure can be adapted to lamp shades 3 manufactured by both injection molding and blow molding processes. In production, there is no need to develop different lamp body 1 molds for lamp shades 3 with different processes, which greatly reduces the mold development cost and cycle, and lowers the overall production cost.

[0049] (2) Convenient and efficient assembly: The design of the guide 5 enables "foolproof" alignment, making the assembly process simple and fast, without the need for complex tools or fine adjustments. The guide notch 53 on the guide 5 facilitates manual confirmation and segmented operation during assembly, improving the success rate and efficiency of assembly.

[0050] (3) Secure and reliable connection: The buckle plate 21 is connected to the lamp body 1 through the rib plate 22, which greatly enhances the mechanical strength and deformation resistance of the buckle part 2. The buckle part 2 and the latch part 4 are evenly distributed along the circumference to ensure that the lamp cover 3 is subjected to balanced force and has a stable structure after connection. In addition, the guide part 5 not only plays a guiding role, but also forms an internal limit for the lamp cover 3 after assembly, forming a double fixation with the outer buckle part 2, effectively preventing loosening.

[0051] (4) Beautiful and practical structure: By designing the annular recess 32, the outer wall of the lampshade 3 and the lamp body 1 can form a smooth and continuous surface after assembly, without any abrupt steps, and the appearance is neat and beautiful. The L-shaped guide plate 51, rounded corners and other details enhance the structural strength and assembly smoothness, while avoiding the risk of possible scratches, thus improving product quality and user experience.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
